I would suggest using 'AFTER update' and 'AFTER Insert' trigger on your custom object.

Have you thought about using a workflow to accomplish this? You could create the workflow to update a field based off of the record type you choose

Hi David,

list< custom_object__c) = select user.name__c from custom_object__c

'NAME' is a standard field for User object.
use:
list< custom_object__c) = select user.name  from custom_object__c
